Welcome to Lost Cavern

What is Lost Cavern?

Lost Cavern eliminates Map Objectives and creates a slimmed-down play area in order to remain laser-focused on one constant, single-lane teamfight. The Hearthstones and Starting Area heals have been removed so that Heroes have no reason to fall back from the fight. Regeneration Orb spawns and brush, meanwhile, have been strategically placed around the lane to keep the fights active and interesting.

We've seen that players have been creating one-lane matches on Heroes' existing maps, so we wanted to create a Battleground that makes things a little easier—and maybe even a little more exciting—for everyone who enjoys these games. Don't let any existing rules stop you from coming up with your own new way to play, though, as Lost Cavern is meant to be a free place to experiment and play however you like. Think of this map as a sandbox in which you can express yourself creatively—as well as have fun playing. Lost Cavern will be launching with our next major patch, and we can't wait to see what you come up with!
